lwlPRovlaMFMTv IN Llei-[Tine ATTacHMENTs'I-'QR ALARM-CLOCKS.

The. Schedule referred to in these Lettere Patent and making part of thesame,

To all whom it may concern.-

Be it known that I, HENRY X. WRIGHT, of VMemphis, in the county of`Shelby and in the State of Tennessee, have invented an Improved Lamp orCandlelightingAttachment forAlarm-Clocks; and do hereby declare that thefollowing description, taken in connection with the accompanying drawinghereinafter referred to, forms a full and exact specification l of thesame, wherein I have set forth the nature and class, together with suchparts as I claim and desire.

to secure by Letters Patent.

My invention relates to attachmentsgto alarmclocks, and consists inproviding 'the alarm attachment with a trip-shaft, friction-disk,lmatch-holder, and lamp or candle-holder, so that when the alarm goes offa lamp or candle is immediately lighted.

The constructionand operation of my invention may be described asfollows:

In the accompanying drawing which forms a part of this specification-Letter A represents a motive or driving-wheel of the alarm attachment,with the bolt or trip-pin a, firmly fixed and projecting from it. V

B designates the trip-shaft placed in a horizontal position, andextending through the casing b of the clock, the shaft being bent orhooked at the inner end c, and loosely supported by the casing so thatitl may slide outwardly or inwardly.

0 lis the friction-disk, which is circular inform and beveled at thecircumference, whereit is' serrated for the purpose of causing friction.The disk'O is rigidly' Maly/nml..

clock-casing, and may be made of wire, as shown in the drawing.

v .The lamp-lighting attachment is cperated in this A wlse:

When the alarm attachment is wound up and set fthe lamp-lightingattachment is wound up with a key,

indicated at letter O, and' the trip-shaft B is moved to thefriction-disk C, the extremity of the shaft entering an aperture in thedisk, indicated at letter u; a friction-match, or other fuse susceptibleof ignition by friction, is then placed in the holder D, so that the endto be ignited bears against the serrated or milled edge of the disk C,the holder serving as a spring for this purpose; the candle or lamp isset in .the holder E so that` the wick touches, or nearly touches,ithematch above, as shown in the drawing. At the point of time when thealarm operates, the trip-pin a, striking against the hook c, instantlywithdraws the tripshaft B from the disk G, which is rapidly revolved bythe spring m, communicating by toothed wheel and pinion with the shafte, thus causing sufficient friction to ignite the match by which thecandle is lighted.

I am aware vthat appliances have been heretofore applied to alarm-clocksfor the purpose of lighting lamps or candles at a certain hour, or whenthe alarm is sprung, (see the patent ,granted to NV. H. and R. T.Andrews, September 21, 1852.)v

I therefore claim and desire tosecure by Letters rl`he. arrangement ofthe wheel A, provided with a trip-pin, c, trip-shaft B, spring m, shaft6,'friction-disk C, match-holder D, and candle-holder E, when operatingtogether as and for the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand this23d day of September, 1870.

Witnesses: HENRY X. WRIGHT.
